There is a German Stalingrad movie from 1993, that is good. A Russian Stalingrad movie came out a few years ago. And Thomas Kretschmann (FEIGELEIN!) was in both the German and Russian "Stalingrad" movies.
You’re right that 93 German film is so great but please do check out the 1959(?) German film I mentioned you won’t be disappointed...there is also a Russian film from 1949 called The Battle of Stalingrad....you will not believe the amount of equipment and mower employed in that film both are free on YouTube . I suspect the 1949 Russian film used actual German prisoners and captured equipment....its unreal
Thomas Kretschmann also played a German officer in THE PIANIST...
Have you seen CROSS OF IRON? It is about Germans fighting on Eastern Front...
